To automate the task of growing vDisks on multiple classes of VMs using Nutanix Playbooks, the administrator should follow these steps:

Create a custom Alert Policy:

Create an alert policy that triggers when the server's disk usage reaches 85% or above. This ensures the playbook is triggered based on the specified threshold.

Select Alert as the trigger:

Set the alert created in step 1 as the trigger for the playbook. This ties the alert condition to the execution of the playbook.

Select Email Action with custom message:

Add an action to send an email notification. This email should be sent prior to any work being started, to inform relevant stakeholders about the impending vDisk growth operation.

Add Action to Grow vDisks:

Add the action to grow the vDisks on the VMs. This step should include the necessary script or task that performs the vDisk growth operation on the specified VMs.

Based on the requirements and steps, the playbook should be structured as follows:

Step 1: Create a custom Alert Policy

Define the alert policy with the condition that disk usage on the VMs reaches 85% or higher.

Step 2: Select Alert as the trigger

Use the alert policy created in Step 1 as the trigger for the playbook.

Step 3: Select Email Action with custom message

Add an email action to notify relevant stakeholders before the vDisk growth task is initiated.

Step 4: Add Action to Grow vDisks

Include the necessary action to grow the vDisks on the VMs as required.

This structure ensures that the playbook is dynamically responsive to changes in server usage, sends notifications prior to execution, and performs the required vDisk growth operation automatically.

An HTTP task is a type of task that can be added to a blueprint or a runbook to perform REST API calls to external systems. An HTTP task can be used to reserve an IP address in the IPAM system before deploying a VM or an application, by sending a POST request with the required parameters and headers. The HTTP task can also capture the response from the IPAM system and store it as a variable for later use. This is the simplest and most efficient way to integrate with an IPAM system, as it does not require any additional configuration or scripting.

To trigger a series of actions (taking a snapshot, expanding the vDisk, and sending a Slack message) from a pipeline CI/CD, the appropriate trigger to use is "Webhook." Webhooks allow external systems, such as CI/CD pipelines, to trigger playbooks in Nutanix Calm via HTTP requests, making them suitable for integrating with CI/CD tools.

 A time trigger is a type of playbook trigger that allows the user to specify a schedule for running a playbook. This trigger is useful for automating tasks that need to be performed periodically or at a specific time. A manual trigger requires the user to initiate the playbook execution manually, which is not ideal for a recurring task. A report trigger is a type of playbook trigger that allows the user to run a playbook when a specific report is generated. However, this trigger does not guarantee that the report will be generated on the first of every month, as it depends on the report settings. A wait until day of month action is a type of playbook action that pauses the playbook execution until a specified day of the month. This action is unnecessary if the playbook already has a time trigger that specifies the desired schedule.

The port 5986 is used for PowerShell Remoting over HTTPS, which is a secure way of executing PowerShell commands on a remote Windows VM. Calm uses PowerShell Remoting to run scripts on Windows VMs as part of the blueprint actions. Therefore, the port 5986 needs to be opened on the VM firewall to allow the communication between Calm and the VM. The other ports are not related to PowerShell Remoting, as they are used for SQL Server (1433), Remote Desktop Protocol (3389), and PowerShell Remoting over HTTP (5985). References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) 6.5 Exam Blueprint Guide, page 10; Nutanix Certified Professional - Multicloud Automation (NCP-MCA), section 3; Nutanix Calm User Guide, page 93.

Runtime variables are variables that can be modified by the Consumer during the deployment of a Blueprint or after the deployment is complete. They allow the Consumer to customize the attributes of the infrastructure and applications according to their needs. Runtime variables can be defined in the Blueprint settings or in the Blueprint YAML file. They can also be used in the Blueprint tasks to pass dynamic values to the scripts or commands. Runtime variables can be of different types, such as text, number, boolean, list, or password. They can also have default values, constraints, and descriptions to guide the Consumer.

Playbooks are a collection of tasks that can be executed on demand or based on a trigger. There are two types of triggers available for executing Playbooks: manual and alert. A manual trigger allows you to run a Playbook on demand from the Prism Central UI or the Calm API. An alert trigger allows you to run a Playbook automatically when a specific alert is generated by Prism Central or a third-party system. Report and audit are not valid trigger types for Playbooks. References: Nutanix Multicloud Automation Administration (NMCAA), page 9; Nutanix Certified Professional - Multicloud Automation (NCP-MCA), section 1.

A Developer permission level grants access to create, update, delete, and duplicate blueprints in Nutanix Calm12. A Developer can also launch, manage, and delete applications from blueprints, as well as create, update, delete, and duplicate runbooks2. A Consumer can only launch and manage applications from blueprints, but cannot modify them2. An Operator can launch, manage, and delete applications from blueprints, as well as run and manage runbooks, but cannot create or modify them2. A Domain Admin can perform all the actions of a Developer and an Operator, as well as manage projects, categories, and endpoints2. References:

 The styx.log file contains the logs related to blueprint packaging and deployment. It can be accessed by SSHing to Prism Central and navigating to the /home/calm/log directory. The other options are not relevant for blueprint package failures, as they show the application status, audit events, or service logs. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) 6.5 Exam Blueprint Guide, page 9; Nutanix Certified Professional - Multicloud Automation (NCP-MCA), section 3; NCP-MCA Exam Dumps - Nutanix Certified Professional - Multicloud …, question 63.

The error message in the exhibit indicates a mismatch between the number of network settings and the number of NICs on the VM. This is a common validation error when saving Calm Blueprints for VMware, where it is essential to ensure that these configurations match to avoid issues with VM deployment and operation1. References: 1: Nutanix NCP-MCA Certification Exam Sample Questions2
